Application filed -Gctober "20, 1913. Seriai No. 796,294.

- may be easily opened or disassembled. to give access to the warm-airchamber and to the heater, for the purpose of cleaning said chamber andfor repairing the heater.

A further object is to construct said casing; in the manner of anadjustable frame and detachable or movable easing-sections co" operatingtherewith, whereby the casing structure may be adapted to meet readilvarious designs of furnaces.

It is my object also to construct a c; ring frame for carrying theabove-mentioned .de

tachable sections, which frame, after said sections have been removed ormoved from their normal position to give access to sub stantially theentire area of warm-air chamber, will support the furnace hood and itspipeconnections without causing derangement of same, this framestructure presenting an open web-like appearance.

These features cooperate in giving a furnacehaving high sanitaryqualities and one which gives very efficient service because of the factthat it can be easily maintai ed clean and its air passagesunobstructed; and further, one which reduces expenses in upkeep, becausewhen repairing is needed for the heater it is accessible without thegreat expense of tearing down a fixed and integral furnace casing.

In furnace structures now in common use it is the custom to provide acasing for inclosing the heater, the casing of such an integralstructure that when, because of various defects that occur within thecasing ither to the warm-air chamber or'to the urnace, it becomesnecessary to gain access to said chamber or to repair said heater anoften difioultt and expensive task is prei because the fixed casingistructure riiustlbe torn down to repair the injuryim side and rebuiltagain when assembling. For this reason the fact is prevalent that veryfew furnaces are maintained, in proper working order to give eiiicientservice. And because of dust, lint and other dirt particles accumulatingwithin the: varm-air chamber,

the passages. thereof become so restricted that the air circulation isgreatly impeded, and more important, such circulation be cause of saiddirt accumulations is reduced to a very unsanitary state.

In my improved furnace structure embodying novel features above setforth, it is evident that the defective features of integrallyconstructed casings and such as are diiiicult to disassemble, areentirely'eliminated.

in, the accompanying drawings: Figure l.

Fig. i is a detail sectionalview taken on the line of Fig. 1. Fig. 5 is horizontal detail sectionalview as taken on the line 5--5 of Fig. 1. Fig. 3 is a detail view inperspective of an end. of supportingbar.

The heater 6 of the furnace maybe of suitable structure and in thisinstance I have illustrated the heater with an associated furnace-front7 having a fire-d0or 8 and ash-pit door 9, said furnace-front eX-tending from a base 10 to a horizontal top ring 11 which is partlysupported thereby. The furnace-front has flanges 12 extending lengthwiseat its sides, and a middle ring 13 has its ends boltedth eto, thuspartly supporting said ring. Said top and middle rings are of similarconstruction, being shaped in cross-section with a vertical por tion 14forming the ring, and an outwardly extending flange 15, the outer s desof the ring forming casing receiving faces. A plurality of verticalsupporting bars spaced apart about the rings are interposed beitween therings 11 and 13 anQ- ring i3 and.

f'l'fhave shown"the casing divided into six sections (the furnace-frontconstituting one) by fourof thesebars; the bars being holte d' 'to'therings in a'set position; but it evident that any'suitablenumb'erof'divisienernay benmd'eand of suitable width by the se of a'greaterior less number of bars, since the bars are slid ably mountedupon the riiwg 's; asuabcive "mentioned.

This holding means is adaptedto secure the sections in place toprovide a close fitting casing and on'e'in which the sections can beeasily re mews; aiid it will be noticed that the outer has of thebarsthat receive the casingvsec: tions are coincident with the outer face ofthe rings 11 and 13, thereby permitting a continuous casing receivingface between said members. In some furnaces the furnace-front 7 does notextend up to the top ring; orpartition therefore the intermediate spaceab e said front could be provided with; a'de'tachable section such ashas been described. Attached to the inner sides of said-"sections arecorrugated linings. 23 whichTprovidc dead-air space to break the chillor the outer casing.

, The manner in "which I have herein. shown the bars adjustable and thecasing sections attachedv "thereto might be deviated .irotn to procurethe equivalent result, and the sections might be hinged or provided withcatch'ieu-gcag'cmcnts with the bars. It might be desirable to-eliininate the middle ring 13 thereby having but single bars extendinghumane hose to the top ring, or. have a portion er the casing ofintegral structure and =a-portion exendirig around the casing ofsectional structure; and it is-evident that mosses sections can be madeinto a casing in such various forms as to suit the most diversifiedrequirements...

"With a furnace embodying a structure'o'f casing of the above character,itfwill be readily seen that when dirt or refuse accumulates in anyportion of thewarin a'ir removingthe necessary c'asing' sections to gainaccess -to said obstructions.

I claim as my invention: 1. In furnace, an outer casing includingplurality. of spaced vertical supports, each having a socket therein atits opposite ends, said support being in supporting engagement with saidcasing-members by the latter being received in said sockets; whereby thesupports may be moved sidewise upon lateral displacement, andcasing-sections de; tachably, mounted and interposed between adjacentsupports. i
